The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing has been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water protection relative to protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is usually tighter tolerances, so all around the gear is a tighter, more precise match. And the tighter fit means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of training course, precision gears are more costly, if the application demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically completed by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly set up. This also worm drive servo china eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, some gear types such as strain wave gears, or harmonic equipment drives, possess zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque ideals, the input stage is usually dimensionally smaller than the output stage. Its short design makes the GSD range the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is required. The flange output creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series offer the same advantages as the GSB line; the right angle shape makes the GSBL range the perfect match for all dynamic applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-stage motors used in combination with a single-phase AC power and three-phase motors used 
with a three-stage AC power. A single-phase motor can be operated by simply linking it to a single-phase power supply via the provided capacitor. A three-phase motor does not require a capacitor. All you have to is to connect the motor right to a three-stage AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly ideal applications for the brand new range are those that place the best demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines include precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
